 Test #9233 in perf/compiler/T9233

 Summary:
 Ideally, we could use Phab's numbers to set the perf
 test correctly. But even if that's not possible, then I need help
 writing my `all.T`. With the version you see here, I get the following

 ```
 Traceback (most recent call last):
   File "/Users/rae/Documents/ghc-valid/testsuite/driver/testlib.py", line
 801, in do_test
     result = func(*[name,way] + args)
 TypeError: multimod_compile() takes exactly 4 arguments (6 given)
 ```

 I don't know how to fix this.

 Test Plan: validate
